+3 to +4 high rpm power

2 Piece Superflare V Stacks - absolutely the Best.

Best airflow.  Best power.   Best intake sound.

Slip these new Factory Pro designed 2 piece intake stacks into your airbox - no cutting or drilling - just a small #1 Phillips screwdriver and normal hand tools required.
These are not like the one piece Graves stacks.

Factory Pro's SuperFlare R6s Stacks have a highly refined, 2 piece design that allows for a full radius, airflow increasing flare - unlike the standard Factory Pro "XS", Graves and GYT stacks.

We don't use dealership level dynos for R&D

 VEL-Y80-SF0  Superflares
3-4 True HP in the upper mid and overrun and even more topend than the 1 pc  GYT or the below STD stacks

2007 December 6

I installed the Superflares on  my 04 r6 and they kick some awesome tail.
Feels like my bike gets to redline a lot quicker and smoother. I run my bike pretty hard and often through the entire rpm. I had wanted to know what would be the best spot to set my shift light indicator so that I don't lose power by revving to high before shifting. below is what I have done to my bike (if that makes any difference :)

1-k&n filter
2-new spark plugs (forgot what kind)
3-micron high mount exhaust (slip on)
4-15/48 gear setup 520 chain

  Thank you very much    Anthony
again sweet work on that creating these stacks!!!!

We still make... The ORIGINAL design one piece Factory Pro stacks for a $100. See below.
Almost as good as the Superflare's.

Factory Pro STD V-Stacks

+1  True HP at 13k, +5  True HP at 14k, +4  True HP at 15k

 Red = Factory Pro's V Stacks  Blue = Stock Yamaha stacks

Peak power increase even w/ stock exhaust.
2 to 3 PEAK True HP

From Factory Pro - designer of more MC Performance V-Stacks than anybody in the world - No copies - no imitations - no real usable factory hints.

Easy to get, quick to install  -  a straighter power curve + a big triangle of upper rpm power that wasn't there before.

Recommended to use all 4 for drag racing or road racing or street.....
Anybody who says different is, well... ummmm....   wrong. The stock stacks don't really add anything significant to the STOCK powerband - (yes - that's a redumbnent statement) and the billet stacks don't hurt an untuned or properly tuned R6s.... So.... if the billet stacks don't hurt the stock v stack powerband.... how could a bike with 2 stock stacks be better in the midrange than a bike with 4 billet stacks? Sigh... some manufacturer's claims baffle me......

30 minutes to install and only $100

Ignition Timing Rotors

(we have small stock of: +2 or +6 avail:
 $10 additional)

Ignition Advance Rotor.

+4 degrees advance adds power at ALL part throttle positions.

That equates to more "snap" in throttle response for you! Makes full throttle, 1st gear, when properly jetted, silly. (as if it wasn't already....)

Most bikes will gain 1-2hp at full throttle at various rpms when measured on the Low Inertia EC997 Eddy Current Dynamometer and when ridden in the real world.

MUST DO - Picks up some of the power that is lost at low rpm / full throttle when the "EXUP" system is removed.

Maximum benefit is gained with a properly tuned FI bike.

For best results - tune to BEST POWER - not "A/F Ratio" power losing settings on "dealership level" dynos.

The extension of the laboratory for engines of the Swiss Federal Institute of Technology was completed in about 1935. Its architect was Rudolf Otto Salvisberg (1882-1940). He had a successful career in Berlin but returned to Switzerland after the advent of the Nazis. His architectural style was somewhat similar to that of Erich Mendelsohn. The staircase of the laboratory is in normal use but well preserved.
